WIRE LATHING.

SPECIFICATION forming part of Letters Patent No. 372,819, dated November 8, 1887.

Application filed June 20. 1887. Serial No. 241,883. (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. SACKETT, a

citizen of the United States, residing at New York, in the county and State of New York, have invented a new and useful Improvement in Wire Lathing, of which the following is a specification. I My invention relates to an improvement in wire lathing; and the object of my invention is to provide a new article of manufacture made by the insertion in ordinary woven or netted wire-cloth, and at stated distances, of a thin flat strip of metal or equivalent material, flexible in the direction of its least diameter, but stiff and inflexible in the direction of its breadth.

To provide a surface for lathing which shall not only be light in weight, but shall also present' great stiffness and be capable of supporting a weight and pressure out of proportion to the resistance of ordinary wire lathing, is the aim of my invention. There have been some attempts previously to achieve this; but although such attempts are improvements over ordinary wire lathing, their use has been restricted by many disadvantages; In one kind of such improvement ribs or V-shaped bars are inserted during the weaving of the structure. The bars are necessarily heavy and bulky, theyare hard to insert, and can only be inserted in process of weaving by stopping the loom at the proper intervals and inserting them in a direction across the meshes of the continuous fabric, and, owing to the thickness difficulties in weaving, and it is heavier and more bulky and cannot sustain the weight and pressure of which the V-shaped insertions render the firstnamed lathing capable.

I have found that by. inserting thin fiat in the meshes of ordinary woven wire-cloth,

each strip separated at a set distance from the others, and if the compound structure thus produced be bent or corrugated into ridges at which each flat strip is held vertically to the plane of the wire-cloth, a new lathing will be produced which will possess every desirable quality of alight and strong lathing and be free from the defects of the wire-cloth heretofore used.

The Wire fabric with my improvement is illustrated in the accompanying drawings, in

which similar parts in the several views are designated by similar letters.

Figure 1 is a view of ordinary wire-cloth. Fig. 2 represents the stiffenera thin flat flexible strip of metal or equivalentv material. Figs. 3, 4, and 5 are cross-sections of various forms of wire lathing embodying my improvement.

The meshes of any ordinary wire-cloth, A A A, are crimped, ridged, or corrugated at the points 0 O G where the flexible strips B B B were interwoven or inserted. Owing to the flexibility of the flat strips, they may, if desired, be woven in continuously as strands in the direction of the length of the fabric with little or no more trouble and expense than is met with in making plain wire-cloth, and the fabric can be handled and rolled up after such strips are woven in with the same ease as if they were not inserted; or, if inserted after the time the cloth is woven, their thinness and flatness rendertheir insertion in either direction into the meshes or into the folds, crimps, or ridges of the wire-cloth comparatively easy.

After inserting such thin fiat stripsrkpass the wire-cloth with the strips of flat metal inserted at regular intervals through any suitable machine, (such as rollers grooved so as to form vertical crimps or ridges of sufficient size to hold the strips vertically therein,) which will form it into ridges at the points where the flexible strips are inserted in such a manner as to bring each strip to a vertical position in regard to the plane of the uncrirnped portions of the wire-cloth; or I first form the ridges in question in the plain wire-cloth and. then insert the strips in a vertical position.

The use in my structure of flat strips thin zoo enough to be flexible in one direction, but broad and stilfin the transverse direction, is much more advantageous than the structures previously described,because,with less weight of metal, much greater stiffness is obtained,and the labor and expense of making the compound structure is less, and it presents no obstacle to a perfect and continuous key.

By means of my invention a difficulty experienced with V-shaped stiffenersis obviated, which is that their shape was such as to pre vent them from being held vertically, and therefore made them liable to be flattened out by blows or pressure, the meshes being thereby spread and the tension of the structure altered, the stiffness being also destroyed in a large degree.

\Vire-cloth made with my improvement presents a surface for lathing the tension of which is evenly distributed, and it will resist more firmly, by reason of the breadth of the thin stiffeners, the weight of the adhering plaster and the pressure of the trowel. Longer distances may be spanned, owing to the possibility of inserting such thin strips lengthwise in the fabric, and the lathing is readily attachable to the bearings by stapling or other fastening, which may also assist in holding the stiffeners in vertical position.

What I claim as my invention, and desire ta secure by Letters Patent, is

1. As a new article of manufacture, a wire lathing consisting of a flat surface of wire meshes stiffened by a series of thin flat flexible bands held in a position vertical to the plane of the lathing at ridges formed on such surfaces, substantially as described.

2. The process of forming wire lathing, which consists of, first, inserting fiat flexible parallel strips of stiffening material in the meshes of wire fabric in the direction of the length of such fabric during the process of formation, and, second, crimping the fabric into ridges or corrugations, so as to hold such strips vertically to the plain surface of the fabric, substantially as described.
